Reaction Steps

A solution of 3-(1-Methyl-1H-tetrazol-5-yl)-5-nitro-benzoic acid ethyl ester (6.5 g) in EtOAc:ethanol (1:1, 320 ml) was hydrogenated at 20° C. and 50 psi with 10% Pd/C (750 mg). After reaction completion, the mixture was filtered and the filtrate concentrated in vacuum to give the title compound (4.2 g). Rt=1.21 min (method D).
